Heterogeneity in numbers of MalS-GFP foci in phase-bright dormant spores^a

Spore sample (B. subtilis AR71)	No. of spores analyzed		% of phase-bright spores with 0 to 3 foci
	R1	R2	0	1	2	3
MOPS
D2	37	48	29	41	27	3
D4	71	52	24	38	34	4
2× SG
D2	49		18	39	23	20
D4	69		67	13	15	6

^aNumbers of MalS-GFP fluorescent foci measured in the dormant (time zero) spores prepared in MOPS and 2× SG medium are presented. For spores prepared in MOPS, the numbers represent averages of results from two biological replicates (R1 and R2). D2 (day 2) and D4 (day 4) represent the age of dormant spores.
